A consumer must consider that when buying a UV system you are buying "water confidence". In order to ensure that confidence, the correct replacement lamp is vital to the continued performance of that piece of equipment. That being said if you buy a specific model it is imperative that you replace the lamp with one that has been designed for that model, otherwise how do you even know that the UV system is disinfecting your water?
There are companies in the water industry that are selling "knockoff" lamps targeting residential UV systems that are sold world wide. These lamps are being offered at a very low price with the promise that they operate the same as the UV manufacturer's lamps. This promise is untrue. If a consumer were to install a "knockoff" lamp the "water confidence" that was being offered by the UV manufacturer no longer holds true and cannot be supported by the manufacturer and voids the warranty on Viqua systems. H2O provides only original UV Max and Sterilight Replacement Lamps.

Activated carbon block is a blend of fine activated carbon, water, and a suitable binder that is mixed and molded and hardened or extruded to a cartridge filter of any size and shape. Sometimes specialized media are added along with activated carbon to provide customized performances for specific contaminants.
The binder is particularly designed and chosen to hold the carbon and other media in a fixed solid matrix, yet, not to plug up the pores of the activated carbon. Even though the binder does occlude a portion of the adsorption sites, the finer mesh size gives activated carbon block filters faster adsorption kinetics and generally two to four times greater adsorption capacity than equivalent volumes of loose granular activated carbon.
Activated carbon block filters typically have a 0.5 to 10 micron filtration capability, making it also helpful for particulate filtration, removing taste and odor from chlorine, insoluble lead reduction, and demonstrating, in some cases, removal of Giardia and Cryptosporidium.
